“…Such a feature enables the Sbw system to have advantages over a conventional steering system in terms of improved driving comfort and enhanced vehicle handling. 3 In addition, the steering wheel in a Sbw system may be substituted by some advanced drivervehicle interface, for instance, a joystick. 4 To use a joystick as an alternative to a steering wheel in a Sbw system may help further optimize cabin space utilization, reduce the risk of injury to drivers in collisions and integrate sophisticated vehicle dynamic control functions.…”

“…Heathershaw 7 proposed a steering ratio design method that reduces the level of 1 vehicle understeer so as to increase vehicle characteristic speed during cornering. Tajima et al 3 proposed the concept of ideal steering ratio which is derived from a speed-independent vehicle lateral response gain. The performance of the ideal steering ratio was validated through experiments using a driving simulator.…”

Steer-by-wire system has replaced the conventional mechanical linkages with electronic actuators. In this article, a joystick is utilized to substitute the conventional steering wheel and study the variable steering ratio design methods in this new human-machine interface. With this structure of steer-by-wire system, the steering angle and torque ratio can be designed flexibly. A dynamic model of joystick of steer-by-wire system is built based on bilateral control scheme. Through comparing the vehicle steering performance of joystick with steering wheel, three conventional steering ratio design methods are studied that are speed-dependent, speed-and angle-dependent and constant yaw rate gain. The drawbacks are analysed by three kinds of conventional steering ratio, and a novel variable yaw rate gain steering ratio design method is investigated. A driving simulator is used to verify and compare these steering ratio design methods. The computer simulation and experimental test results demonstrate that the variable yaw rate gain steering ratio design method can effectively guarantee vehicle steering performance.

The automotive steering system plays an important role in determining the behavioral dynamics of the operator/vehicle interface. The system's primary function is to transmit the driver commanded steering wheel angle to the road wheels; The secondary function is to provide tire/road interface information back to the driver. The automotive chassis engineer needs a design tool to evaluate the effect of steering parameters on overall vehicle lateral behavior. In this paper, a real time steering simulator will be presented to emulate the behavior of automotive steering systems. The re-configurable steerby-wire simulator allows for the emulation of steering systems ranging from hydraulic, electric and steer-bywire in passenger, light duty, and commercial vehicles for pre-production and production models. To validate the simulator's functionality, a case study has been performed with numerical and experimental data. Comparisons between the simulator results and field data demonstrate a high level of correspondence. The re-configurable simulator evaluation tool represents a contribution to the field of automotive design.

“…There are a few measures in the literature to describe the physical workload. In the work of Tajima et al [45], the magnitude of physical workload is calculated by the integral of squared steering wheel angle rate. For this study, a new measure, the integral of steering power, is introduced in order to incorporate the steering wheel torque into the calculation of workload:…”

A mathematical model of steering feel based on a hysteresis model is proposed for Steer-by-Wire systems. The normalized BoucWen hysteresis model is used to describe the steering wheel torque feedback to the driver. By modifying the mathematical model of the hysteresis model for a steering system and adding custom parameters, the availability of adjusting the shape of steering feel model for various physical and dynamic conditions increases. Addition of a term about the tire dynamics to the steering feel model renders the steering wheel torque feedback more informative about the tire road interaction. Some simulation results are presented to establish the feasibility of the proposed model. The results of hardware-in-the-loop simulations show that the model provides a realistic and informative steering feel.
